LEVER CHOGK.

Aliplication med April so.

To all whom t may ,concer/11,:

Be it known that I, OMER C. GoULE'r, 'a citizen of the United States, residing at Fall River, in the county of Bristol vand State of Massachusetts, have invented `certain new and useful Improvements in Lever Checks; and I do declare the following to i be a full, clear', and exact description of the invention such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved de-I vice which may be conveniently referred to as a lever chock, the office of the device being to hold a rod shifting lever of a folding machine or the like in a set position.

It is the principal object of the invention to generally improve upon devices of this class by providing onewhich is practical, reliable and positive in action, and comparatively simple in construction.

More specifically speaking, it is an object of the Yinvention to simply equip the usual lever mounting bracket with an integral ear which provides a shoulder, and to pivotally mount a supplemental lever or chock 'on the main lever for co-action wit-h the shoulderto maintain the shifting lever in a set position.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawing forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is a perspective view of a portion of a well known type of folding machine showing the application of the lever chock to the belt shifting lever.

Figure 2 is an enlarged sectional view with parts in elevation, showing the construction more clearly, the chock being shown in operative position.

Figure 3 is a View similar to Fig. 2 showing the parts in their normal ineffective position.

Figure 4 is a detail elevation, with portions shown in section showing the association of the two levers more clearly.

In the drawings, the letter F designates generally a portion of a conventional type of frame on a well known folding machine. yAs is usual, a horizontal belt shifting rod R is slidably mounted on the frame and is 1923. Serial No. 635,738.

reciprocatedv byy movement o-f lthe leverl L which is pivotally mounted on a bracket B secured to one legof the frame. As is obvious, when the lever is rocked upon its pivot, the rod R is moved for shifting the belt A from one pulley pulley. As these parts and operation are well known, no further description thereof need be entered. f

As before intimated, the invention resides inthe association of unique means with the leverL for maintaining it in a set position whenthe belt .isshifted ontok the rigid driving pulley. The preferred me-ansfor accomplishing this result comprises a supplemental chock lever l provided between its ends with a pair of spaced ears 2 having pivotal connection with a portion of the main lever L at points above its pivotal connection with the mounting bracket B. The lower end Seof the chock lever is substantially wedge-shaped and is adapt-ed to be engaged with an integral lug or ear 4 carried by the aforesaid bracket. Speciically described, the lug 4 has its outer edge 5 inclined to form a shoulder and the correspondingly inclined surface of the lower end 3 of the lever is adapted to be engaged therewith as seen in Fig. 3 to hold the belt Shifting rod R in a stationary state. So that the chock lever will be substantially automatic in engaging the shoulder, a coiled spring 6 is employed and exerts a yielding pressure against the intermediate portion thereof, the spring being housed in a socket 7 carried bythe main shifting lever.

Assuming that the parts are in the position shown in Fig. 3, it will be noted that the lug 4 is received between the lower end 3 kof the chock lever and the intermediate portion of the main belt shifting lever. If it is desired to retain the shifting rod in a set position` the hand gripping portions of the two levers are grasped and the chock lever is, rocked on its pivot to release its grip from the lug 4. Then the main lever is swung on its pivot until it assumes the approximate position shown in Fig. 2. At a predetermined time, the lower end of the chock lever will pass beyond the shoulder 5 of the lug and when it is released, it will swing into engagement with said 'shoulder and maintain the shifting lever in a set position. Inasmuch as the spring 7 will serve to maintain the chock lever in place,

l?y onto the adjacent there is no chance of it becoming accidentally disengaged :trom the shoulder. v

By carefully considering the description in connection With the drawings, persons familiar with devices of this class Will doubtless be able to obtain a clear understanding of the invention. Therefore, a more lengthy and detailed description is deemed unnecessary.

Since probably the best results may be obtained with the construction and arrangement herein shown and described, this is taken as the preferred embodiment of the invention. However, I Wish it to be understood that minor changes coming Within the scope of the invention as claimed may be resorted to if desired.

I claim :v

l. In combination, a lever mounting bracket having an ear thereon forming shoulder, a shifting ,lever pivoted on the bracket at a point beyond said shoulder, said lever having a socket, a spring in the socket, and a chock lever pivoted to the first named lever, said spring exerting yielding pressure against the chock lever so that .it Will automatically engage with said shoulder when the shifting lever is moved outward ly a predetermined extent.

2. A devicek of the class described comprising a lever supporting` bracket having an integral ear on its upper side, the outer edge of said ear forming a shoulder, a rod shifting lever pivoted between its ends on said bracket at a point beyond the shoulder, said lever being provided with a socketin one side, a coiled spring arranged in the socket,`and va chock lever pivoted between itsI ends on the first named lever at a point adjacent said socket` said ear being normally positioned between the levers, and the lower end of the chock lever being automatically engaged With said shoulder when the shifting lever is swung outwardly a predetermined extent.

In testimony whereof I have hereunto affixed my signature. OMER C. GOULET'.
